Specification of `Letters Patent.

Patented raar. it, asia.

To all who-m it may concern Be it known that l", Max M. Conn, a citizen of 'the United States, residing at Piedmont, in the county of Alameda and State of California, have invented new and useful. improvements in Ferpetual indexes, of which the following is a specification.

' This invention relates to a perpetual index. A

y a. simple and practical index for oiiice, com- The object of this invention is to provide mercial and home use, which at a glanbe discloses the entire contents-of the index and at the same time, can be changed or added to, Without disarranging the alphaictical or numerical sequence of the indices.

The invention consists of the parts and the combination and construction of parts ashereinater ymore fully described and claimed, having reference to the accompanying drawings, in which-- Figure l represents the simplest, style of blank suitable for practising vthe invention. Fig. 2 represents the preferred form of blank. Fig. 3 illustrates the invention. Fig. 4f is a crosssection on line X-X, Fig. 3. Figs. 5 and G'show index members folded, Fig. 7 is an enlarged diagrammatic section on line.Y-*Y, Fig. ii.

In carrying out my invention I employ a suitable holder, as A, which may be of metal, paper, cardboard, .or of any suitable material, having inwardly turned flanges 'or guides 2, at its opposite side edges, adapted to receive the index members 3. dex member 3 consists simply of a piece of paper folded in such fashion that each strip becomes ka name card capable of having its ends slipped under the fianges', and one name card pushed up beneath and adapted partially toV under-lie a preceding name card, and the fold of the preceding card forming a pocket to receive and guide and limit the upward movement of the card last inserted from beneath. Preferably, the sheet of paper is of suflicient size to be inserted conveniently into a typewriting machine, so as to have the name, or other matter desired, easily typed thereon, without requiring any special appliances for holding the sheet.

ln F ig. l I have sho/wn a blank consisting of simply a square Ipiece of 'paper whose diagonal a represents the length of the index card, formed by folding the blank 3. This blank ,3 isA rst creased on the line a,

and then opened out and then folded on the line' l), parallel to line a, spaced from line a a distance substantially equal tolthe height of the printed name. In the narrow space c formed between the scoring l` es, or creases, a-b, 1s printed the name, ther matter to appear on the index.l Aps thi space c lies substantially between the upper and lower edges of the sheet, it is a simple matter to insert this blank into a typewriting machine and type 'whatever is wantedin this space c. To form an, index card, the sheet 3 is irst folded upon itself, along the line l) in such fashion that the part a will appear uppermost, and a triangular'dap-portion Z will project below and be visible beyond the line This second fold is represented in Fig.

l by the scoring e for that portion of the I sheet lying to one side of the lines a-b. and by the scoring f, for that portion of-the lsheet lying on the opposite side of said ylines a-Tb.

In Fig. 2, which is the preferred form, the same principle is involved, except that the upper and lower portions Aof the sheet of Fig. l are curved so as to make the folded card more easily insertible into place into the holder A. The same reference numerals are applied to Fig. 2 that are applied to Fig. l.

These index blanks 3 when they are made up at the factory, are cut and scored, substantially as shown in Fig. 2; it being understood of course that any suitable shape of blank may be used, and these blanks are `delivered to the customers lat and opened out, but ready for use, and requiring only to be written on and then folded and inserted into V place.

Having folded the blank first on the line b and then again on the ines e-f, thereby cdnstituting the index ca. d, this index card vis slightly bent so that itsV ends may be slipped under the flanges 2 of the holder A, and pushed up underneath a preceding card and into the V-Shaped pocket, formed by the flap (Z and its fold f. The natural springiness of the folded sheet causes the flap portion d to h ug the back of the holder A.. As before stated, this ilap cl preferably is rounded and projects below the scored edge Z) (but not necessarily so) so as to form a convenient guide into the V-shaped pocket for the next succeeding card. The depth of the pocket formed by the flap d and the fue .ne

' .and f.

is just sufficient so'that when a card is slipped in from underneath, the line a of the last inserted sheet or card will be substantially coincident with the line of the overlying card. By varying the depth of the pocket, which can be done by making the fold f nearer to, or farther from the fold b; a correspondingly greater or less amount of an inserted card will be visible. That is to say, the space c lying between the lines a-Z; will vary in width according to the amount that any one card can be pushed up underneath the succeeding card. Except as a matter of convenience and giving demarcation to the index, the line a is unnecessary;' the essential folds being b-e These index cards when thus folded provide as is seen, a V-shaped pocket opening along one edge of the card; the opposite edge of the card being substantially A- shaped, or wedge-shaped, and adapted to fit and be `guided into a succeeding V-shaped pocket. The folding of the sheet on the lines b-c ofl'ers no raw edges. Also, by the method of double fold I am able to use this index card as before described, in an ordinary typewriter and then by simply folding the sheet `on the line (Z, actually have the typewritten or manually written matter at the very edge of the sheet; something that is not possible to do by any form of index on the market, or that I have ever heard of before my invention. i

lVhen the sheet is properly inscribed and folded to form a card, this card is readily inserted 'into the side pockets formed by the :flanges 2 of the holder A.

Havingr thus described my invention, what I claim and desire to secure by Letters Patent is 1. In an index, an index card consisting of a sheet folded on itself to provide a straight edge, the sheet thus folded being again folded on itself to provide a V-shaped pocket on one edge andan A-shaped wedge on the opposite edge adapted to fit in-to the \/shaped pocket of a preceding card.

2. In an index, the combination with a holder havingr parallel opposed guide fianges forming side pockets opening toward each ether, and a series of index cards inserted into said pockets, said index cards each consisting of a sheet of paper folded upn itself to provide a V-shaped pocket on its .underside, said pocket opening toward one edge of the folded sheet, and the opposite folded edge of the sheet being folded to form'an A-shaped guide designed to fit into a pre- -eiling V-shaped pocket.

3. An index card consisting of a sheet of paper folded upon itself and creased parallel to the fold to form an inscription panel and said folded portions again/folded to form a pocket for the reception of a succeeding card.

4. In a renewable index, a series of index cards, each index card made from a sheet of paper which is adapted to have the inscrip tion written across the middle portion of the sheet, the sheet then folded to bring the writing atthe folded edge of the sheet, and to form a Vsshaped pocket to receive and to limit the amount of the insertion o a succeeding folded sheet, whereby each card projects ay predetermined distance beyond a preceding one to expose to view the inscription on all the cards in the series.

5. In a renewable index, a series of index cards, each index card made from a sheet of paper which is adapted to have the inscription written across the middle portion of the sheet, the sheet vthen folded -to bring the` writing at the folded edge of the sheet, and to form a V-shaped pocket to receive, and to limit the amount of the insertion of au eeeding folded sheet, whereby each card pfojects av predetermined distance beyond a preceding one to expose to view the inscriptlon on all the cards in the series, and a holder for the cards.

In testimony whereof I have hereunto set my hand in the presence of' two subscribing witnesses.
